[klr6502k]

my 2000 klr650 has developed a wandering/unstable issue if following any kind of traffic over 90kmh (55mph) within 150 meters(yards) my bike gets very unstable. the handle bars shimmy and the bike goes back and forth as if i was in the draft of a semi truck. even a strong cross wind can cause the effect. it almost feels like the tires are flat but the pressure is fine (32psi) three things happened that may have contributed to this. #1 i stalled the bike out on a small hill and tipped (fell off)over. (nothing broke but i did bend the handle bar guards around a bit) #2 i had a flat rear tire on the highway and had to push it with the flat 200 yards to a safe spot to fix it ( i have checked to see if the rim is warped but there is less than 1.5mm (1/8 inch) off true side to side) #3 when i changed the flat the first time i put it on i had the spacers on the wrong side. tightened it up then took it off and moved them to the right side. i thought it might have been caused by damaning the sidewalls of the tire when i moved it when flat but with new rubber it acts the same. i have checked all bearings and taken the tire off and remounted it, checked subframe bolts are tight.. triple tree is tight. swing arm is tight, shock is tight. i have heard that dumping the bike can twist the frame, but i cant find information how to check. (it was not that hard of a fall) im stumped klr6502k

Just a couple of questions for you. How many miles on the bike, and is this a problem that occurred suddenly, or has it developed over time? Ross Lindberg Fertile, MN

Mine has hit the ground much more and much harder than that My bike did that when my forks were slightly twisted/loose in the clamp. Though... I also had the rear tire changed and balanced at that time

weight distribution can cause that as well, on a KLR most notably when there is too much on the front vs rear. Experiments to try: take it up to where the instability begins, then shift rearward on the seat 6-8 inches... does it make a difference? drop the rear preload adjustment to its lowest setting... any change? if either of those things help, consider putting some preload adjusting shims in the front. -Jeff Khoury Astatic Solutions, LLC.

And it didn't do this before? My firs thoughts are that the front fender is stock and catches the wind. 2nd, your tires are getting worn. 3rd, you have really aggressive tires. Did you pack more stuff in the back? Mine gets a little twitchy sometimes at high speeds with odd winds, so if I lean over the tank a bit and get more weight over the front it stabilizes a bit. -----Original Message----- From: DSN_KLR650@yahoogroups.com [mailto:DSN_KLR650@yahoogroups.com] On Behalf Of klr6502k my 2000 klr650 has developed a wandering/unstable issue if following any kind of traffic over 90kmh (55mph) within 150 meters(yards) my bike gets very unstable. the handle bars shimmy and the bike goes back and forth as if i was in the draft of a semi truck. even a strong cross wind can cause the effect.

#1 Try increasing the rear preload ? #2 Check Steering head bearings, maybe loose ? #3 Dropped the bike, myself I put bike on jack, loosened triple clamp bolts enough to get forks to move only, then I spun the front wheel as fast as I could by hand, and grabbed a whole handful of front brake to get the forks to straighten out. Re-tighten Pinch Bolts I would try them one at a time mostly just to see what caused the problem. No doubt you are going to get alot of replies on this one, I think it might even be in the FAQ also. I have gotten some wobble, but mostly when loaded weird / air pressures really low from being offroad, sitting way back to far. Honestly do not remember ever getting a wobble since installing the Dunlop D-606 on the front. Good Luck Dooden A15 Green Ape

already tried preload on the rear spring, just as bad if not worse. steering head bearing checked for tightness might be even a little too tight but still swings freely. just tried loosening triple clamps (and the fork brace)and ensured they free and not twisted and re-tightened them. never had wobble like this before on my klr. it gets down right scary. gear on the bike is the same as i always have on the bike. sliding forward or back on the seat makes no difference (im 260 lbs) is been a bad year for problems for this klr. klr6502k -- In DSN_KLR650@yahoogroups.com, "Dooden" wrote:

When you say 1.5mm off true, do you mean that the rim has a runout of 1.5mm or that the whole assembly is 1.5mm offset? The front end of your bike is where I'd be looking. If the rim is warped by 1.5mm, that could do it. Did you balance the front wheel? Since you fixed a flat, the tire could be back on at a different spot, creating a new imbalance. If you drive the bike down a road with no wind and no turbulence, can you loosen your grip on the bars and feel anything wobbly? klr6502k wrote:

back yard testing. with the rear tire and rim bolted in place on the bike with out the chain attached (and blocked up with the rear tire off the ground). when i spin the tire ( and it spins freely and smoothly) if i hold a flat screwdriver on the side of the rim (on the metal rim right at the bead of the tire) hold the screwdriver from moving on the swing arm then slowly spin the tire. the rim hits the screwdriver in two spots (rubs really) and there is ever only a TINY (1.5mm MAX)space between when the screwdriver rubs and does not rub. rear tire. that is. front has even less.
